Once per turn: you can Special Summon 1 LIGHT Machine-type monster from your deck. Monsters other than the Special Summoned monster cannot attack during the turn you activate this effect. If this card would be destroyed, you can return 1 LIGHT Machine-type monster in your Graveyard to the bottom of your deck instead. When this card is sent to the Graveyard: you can target 1 "Cyber" Spell/Trap card in your Graveyard; banish this card and 1 LIGHT Machine-type monster in your Graveyard, then, add that target and 1 "Cyber" monster from your deck to your hand.
